I have a friend over at the moment and we just went for a long bush walk through one of the state forests. She has a 5 month old puppy GSD and when we got home, we put her straight into the backyard (because she's not 100% toilet trained). I had Sammy with me and we had some stuff to carry in from the car to make our lunches with. While we were doing this, we heard the puppy start screaming. I ran outside and Sammy came with me and we found that the next door neighbour's kelpies (they have 2) had escaped into my yard and the male was aggressively harassing the pup. He always barks at Sammy and ran straight at him as soon as he saw him, fortunately leaving the pup.
He went straight at Sammy's neck before we even had time to think, but Sammy dodged it and bum whacked him (best way I can describe). He growled and his ruff went up. The kelpie hesitated but then struck again. This time, Sammy leapt up as the kelpie charged and somehow knocked the kelpie over - it was all very fast. Sammy let him get up but the kelpie spun and tried to bite Sammy on the neck again even as he was getting up and running past. Sammy dodged again fortunately and was now loudly growling in the super deep scary way he has - I started to get worried because you could see he was going to start retaliating pretty soon and he's about twice the weight and size of this stupid kelpie, but the kelpie wouldn't come near me.
The owner of the kelpie jumped the fence and was screaming at his dog. At this point I saw the dog seemed confused so I started yelling at it as well and fortunately it backed off a bit. The owner dived onto it, it wouldn't come to him and picked it up by the scruff of its neck. He apologised profusely and we think we fixed the hole, but I will be getting some concrete put in anyway. The man explained the kelpie was 18 months old, desexed but bites other dogs, even 5 month old puppies which seems weird to me. The other one was an entire bitch, 10 years old with hair missing and wart like growths on its back and tail but completely friendly.
I am scared that this dog will get through the fence again. The owner was worried about our dogs but I didn't think it could really hurt Sammy. I am worried that if I'm not here and it escapes into our yard again, Sammy will defend himself and then what happens? I don't think the guy would press charges, but could he? Where do you stand if someone's dog attacks yours in your backyard but you own the bigger dog and so the other dog, the initial aggressor and the one who isn't securely contained is also the one who gets hurt?
